Computes the Cholesky decomposition of a positive semi-definite matrix.

Main aliases

tf.keras.ops.linalg.cholesky

tf.keras.ops.cholesky(
    x, upper=False
)

Args
`x`	Input tensor of shape `(..., M, M)`.
`upper`	`bool` If True, returns the upper-triangular Cholesky factor. If False (default), returns the lower-triangular Cholesky factor.

Args

x Input tensor of shape (..., M, M).

upper

bool

If True, returns the upper-triangular Cholesky factor. If False (default), returns the lower-triangular Cholesky factor.

Returns
A tensor of shape `(..., M, M)` representing the Cholesky factor of `x`.
